Instances

Each instance is identified by a host and an instance number. This data is stored by the Contract Manager in the instance record. Instance records enable the Contact Manager to transfer requests to specific components of the KCM instance — more specifically, to their host and port.

Instance records are created automatically by the KCM installation.

• When an instance starts, it contacts the Contract Manager, creates its own instance record and associates it with its contract, that is, performs registration.
• When an instance stops, it contacts the Contract Manager and removes its instance record, that is, performs unregistration.

However, if the instance cannot reach the Contract Manager, you can manually complete the registration or unregistration, using the following commands available for the ManageCM tool:

• Register an instance
• Unregister an instance
